Ponzo illusion

Have you ever noticed that when the moon is right on the horizon, it seems more? That's not it. This effect - the fruit of the imagination of our brain. Think about what happens when you see on the horizon of his friends. Although you can see them small, your brain refuses to accept these dimensions. Something similar happens with the Moon. The phenomenon, known as the Ponzo illusion, lies in the fact that the brain distorts the size of the moon and makes it bigger than it actually is. Do not believe me? The next time you look at the larger moon, close all other hands. You see, it is immediately reduced.
